Methods and systems for providing mobile subscriber surveillance
First Claim
1. A method for providing mobile subscriber location information to a surveillance center, the method comprising:
- (a) receiving a first signaling message in a wireless communications network;
(b) determining whether the first message is associated with a mobile subscriber under surveillance by comparing subscriber identification information extracted from the first message with mobile subscriber surveillance watch list information stored in a database;
(c) in response to determining that the first message is associated with a mobile subscriber under surveillance, obtaining location information regarding the mobile subscriber; and
(d) forwarding the location information to a surveillance center.

Abstract
Methods and systems for providing mobile subscriber surveillance identify certain call signaling messages as candidate messages for mobile subscriber surveillance. From the candidate messages, messages associated with mobile subscribers under surveillance are identified. Mobile subscriber location information is obtained for the messages associated with the mobile subscribers under surveillance. The location information is forwarded to a surveillance center, such as a state or federal law enforcement or security agency. The original call signaling messages are forwarded to their intended destinations so that surveillance is performed transparently to the mobile subscriber under surveillance.

20. A triggerless location services routing node, the routing node comprising:
-
(a) a screening module for receiving call signaling messages and identifying call signaling messages as mobile subscriber surveillance candidate messages;
(b) a location notification module operatively associated with the screening module for receiving call signaling messages identified as surveillance candidate messages, determining whether the surveillance candidate messages are associated with mobile subscribers under surveillance, obtaining location information for the mobile subscribers under surveillance, and forwarding the location information to a surveillance center; and
(c) a mobile subscriber surveillance database associated with the location notification module for storing surveillance watch list information usable by the location notification module for identifying call signaling messages associated with mobile subscribers under surveillance. - View Dependent Claims (21, 22, 23, 24, 25, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

26. A triggerless location services routing node, the routing node comprising:
-
(a) a screening module for receiving call signaling messages and identifying call signaling messages as mobile subscriber surveillance candidate messages;
(b) a location notification module operatively associated with the screening module for receiving call signaling messages identified as surveillance candidate messages, determining whether the surveillance candidate messages are associated with mobile subscribers under surveillance, obtaining location information for the mobile subscribers under surveillance, and forwarding the location information to a surveillance center; and
(c) a mobile subscriber surveillance database associated with the location notification module for storing information for identifying mobile subscribers under surveillance, wherein the screening module is adapted to forward the call signaling messages to their intended destinations and to forward copies of the candidate messages to the location notification module, thereby performing surveillance processing transparently to the subscribers under surveillance.

40. A signal transfer point comprising:
-
(a) a link interface module for sending and receiving call signaling messages in a wireless communications;
(b) a screening module operatively associated with the link interface module for identifying predetermined call signaling messages as candidate messages for mobile subscriber surveillance processing, copying the candidate messages, and forwarding the original messages to their intended destinations; and
(c) a mobile subscriber location notification module operatively associated with the screening module for receiving the copied messages associated with mobile subscribers under surveillance, obtaining location information for the mobile subscribers under surveillance, and forwarding the location information to a surveillance center.
